Since these can be changed on the placed light actor they have to be read from there, so this is now a pointer in FDynamicLight, just like the other properties that can be user-changed.
Also did some cleanup on the interface so that external code doesn't need to dereference the lightflags pointer but can use utility functions for all flags.
This did no longer sort sprites in the same position reliably since the feature to render sprites which only partially are inside a sector was added.
With this, sprites in the same position are no longer guaranteed to be added to the render list in sequence.
Fixed by adding an 'order' field to AActor which gets incremented with each spawned actor and reset when a new level is started.
The software renderer will also need a variation of this fix but its data no longer has access to the defining actor when being sorted, so a bit more work is needed here.
* it was never saved in savegames, leaving the state of dead bodies undefined
* it shouldn't be subjected to pointer substitution because all it contains is old dead bodies, not live ones.
Game crashed when any of gl_brightfog, gl_lightadditivesurfaces, gl_notexturefill CVARs is set with no level loaded
There was impossible to reset settings to defaults because of this
* only call hw_CheckViewArea if the result is not known yet.
* check the map up front if it even contains heightsecs. This allows to shortcut the above check entirely for maps without sector transfers and will allow further optimizations.
* the MAPINFO options now get handled in g_mapinfo.cpp and g_level.cpp, just like the rest of them as members of level_info_t and FLevelLocals.
* RecalcVertexHeights has been made a member of vertex_t and been moved to p_sectors.cpp.
* the dumpgeometry CCMD has been moved to p_setup.cpp
This was done mainly to reduce the amount of occurences of the word FTexture but it immediately helped detect two small and mostly harmless bugs that were found due to the stricter type checks.
- moved timer definitions into their own header/source files. d_main is not the right place for this.
- removed some leftover cruft from the old timer code.
This is mainly to support UMAPINFO which does not have clusters but has been extended to define separate exit texts for each target map that can be reached from a given map.
Special names 'normal' and 'secret' can be used to define texts specific to the default exits.
New MAPINFO properties:
* exittext = mapname, "text"...
* textmusic = mapname, "musicname", order
* textflat = mapname, flatname
* textpic = mapname, picname
textflat and textpic are like 'flat' and 'pic' for clusters, one defines a tiled background, the other a fullscreen image.
Setting an empty exittext will disable a cluster-based text screen that may apply to the given map.
